Update to leptonica 1.83.0

ccouzens/leptonica-plumbing#5

It doesn't currently work, but I expect it can be refactored.

```bash
LD_LIBRARY_PATH="$(pwd)/../../DanBloomberg/leptonica/local/lib" PKG_CONFIG_PATH="$(pwd)/../../DanBloomberg/leptonica/local/lib/pkgconfig" bash -c 'cargo test --release && valgrind --leak-check=yes --error-exitcode=1 --leak-check=full --show-leak-kinds=all "$(find target/*/deps/ -executable -name 'leptess-*')"'
```
